Portable Recirculating Air Cleaning System
The Defend 400 is a free-standing, portable recirculating air cleaning system designed for continuous 24/7 protection in healthcare or other commercial settings to provide airborne infection control.
The FDA has cleared the Defend 400 as a Class II Medical Device to filter out and inactivate airborne viruses and bacteria for medical purposes within medium to large rooms and indoor spaces.
The Defend 400 (NV 400) uses WellAir's patented NanoStrike™ technology, combined with a triple-stage Camfil® filter system, to provide a powerful solution for air disinfection and particle removal.
The Defend 400 inactivates aerosolized viruses, bacteria, and fungi and purifies the air of pollen, particulate matter (PM), volatile organic compounds (VOCs), and odors. Proven to reduce and inactivate mold spores, pollen, dust, dander, bacteria, viruses, VOCs and odors.
Developed by the Novaerus team of scientists and engineers, NanoStrike Technology harnesses a range of physical concurrent pathogen inactivation processes to safely disinfect the air. NanoStrike coils provide a powerful strike that works to burst airborne pathogen cells, rapidly inactivating them, helping to ensure they are no longer a threat of infection.
NanoStrike technology harnesses a range of physical concurrent pathogen inactivation process to safely dis-infect the air. NanoStrike coils provide a powerful strike that works to burst airborne pathogen cells, rapidly inactivating them, ensuring they are no longer a threat of infection. NanoStrike attacks, DNA and protein within the cell wall are destroyed and the cell bursts due to osmotic pressure.
